This is the first textbook devoted to the philosophy of psychiatry, offering a thorough and accessible investigation of the conceptual and philosophical problems at the heart of psychiatry. While it applies some of the longstanding concerns of philosophy of science to the mental health professions, it also investigates philosophical problems and issues that have arisen more recently from the practice of psychiatry. Divided into two sections, the book's 11 chapters cover philosophical issues in psychiatric practice and research--like the ontological status of mental illness, philosophical issues in diagnosis, and the relationship of mental illness and personal identity--as well as foundational problems in studying well known psychopathologies, like schizophrenia, delusional thinking, and depression. All chapters include initial overviews and concluding summaries and an annotated list of suggested readings. A glossary at the back of the book provides helpful definitions of key terms in both philosophy and psychiatry.
